TelephonyManager.listen can have notifyNow always true.
Since telepony.registry is a real system service notifyNow
parameter doesn't need to be conditional as telephony.registery
will never go away.
This is different from most of the other TelephonyManager
methods which are used to invoke methods on the phone service
which implements ITelephony and is implemented by
PhoneInterfaceManager in the phone application. Since the
phone app is not a system service it can and does go away when
